"UniVert 2" inverter
Individual INV operation:
Here an INV is supplied with DC and itself supplies the AC load. In
the event of INV fault or switch-off, the load is no longer supplied.
Parallel INV operation:
In order to increase redundancy or performance, up to 8 INVs of the
same type and the same output can be connected in parallel. Note
that if one or several of the INVs fail, the remaining INVs take over
the load. Overload of the remaining INVs can be prevented by
choosing the right number of redundant INVs. If the number of INVs
that fail or are switched off exceeds the number of available
redundant INVs, the remaining INVs switch off together.
When the INVs are switched back on by connecting the DC, they do
not switch on their output contactors at the same time until a sufficient
number of INVs (in accordance with the redundancy setting) are
available to take over the load.
INVs for parallel operation need a choke between INV output and
busbar.
Individual or parallel operation with SBS:
If one or more INVs are combined with an SPS, switchover of the
loads from the mains to the INV and vice versa is possible without
any interruption. With parallel operation systems, the load is
distributed to the remaining INVs if one or several INVs fail. The
system may switch over to the mains when a voltage drop occurs on
the load busbar as a result of the failure of one INV, or if the number
of INVs still operating is insufficient (redundancy setting). In order to
switch the load back from the mains to the INVs, n-R INVs must be in
operation (where R = redundant INVs).
2.2
Function of the System
Individual INV operation:
The INV as an individual unit supplies the loads. If it is switched off or
disturbed, either by internal faults of the INV or by failure of the
DC supply or by a DC voltage deviation, the AC loads are no longer
supplied. The INV is not synchronised with the mains or other
AC voltage sources. The INV can be connected to the DC voltage
using a switching device on the input (miniature circuit-breaker,
contactor). An internal softstart device limits the current to values
below the rated current. If the INV is switched to the DC, the control
unit starts operating. The INV supplies the output voltage if the unit is
additionally switched on using the ON/OFF switch. If the supplying
mains fails, the battery of the power supply system is discharged
(also) by the INV. When the DC undervoltage monitoring value is
reached, the INV is switched off. If the battery is charged after the
mains voltage has returned, the INV is automatically started when a
limit value of the DC undervoltage monitoring is exceeded.
Page 11 of 42
8000012364 BAL, en
"UniVert 2" inverter
Parallel INV operation:
Prerequisite for parallel operation is that the INVs on the DC and AC
side are connected in parallel, interconnected via CAN bus (16-pin,
X7) and correctly addressed. The general behaviour of an individual
INV is as described in the previous paragraph.
The loads are only supplied with voltage when n-R INVs are switched
on. The K7 output contactors of the INVs switch on simultaneously.
The load is distributed equally to all the INVs in operation. If an INV is
switched off or becomes faulty, the remaining INVs supply the load.
The INVs are not synchronised with the mains.
When the DC undervoltage monitoring value is reached, the INVs are
switched off. If the battery is charged after the mains voltage has
returned, the INVs are automatically started when a limit value of the
DC undervoltage monitoring is exceeded. The K7 output contactors of
the INVs are switched on when n-R INVs are in operation.
In order to be able to remove one INV from the interconnected
system for maintenance or repair work, we recommend providing a
DC and an AC fuse for each INV.
Individual or parallel operation with SBS:
Prerequisite for operation with SBS is that the INV and SBS are
connected in parallel on the AC side, interconnected via
CAN bus (X7) and correctly addressed. The general behaviour of an
individual INV is as described in the two previous paragraphs.
Under normal conditions, the INVs are operating synchronously with
the mains and supply the AC loads. In the event of a voltage drop on
the load busbar caused by the short circuit of an AC load or the
failure, switch-off or overload of the INVs, the thyristor contactor of
the SBS is fired and the K7 output contactors of the INVs are
switched off. The loads are supplied by the mains. When the required
number of INVs is available again, the loads are switched back from
the mains to the INVs without interruption. If the SBS is blocked, e.g.
because of mains voltage deviations, it is not possible to switch from
INV to mains or vice versa.
In order to be able to disconnect the SBS from the mains and the
AC busbar for maintenance or repair work, we recommend providing
an AC fuse for both sides and supply the loads via the manual
bypass.

Description of the INV
Its electronic high-performance components make the INV suitable
for universal applications. It has a very high degree of operational
reliability, optimum efficiency and excellent communication capability
with other systems thanks to integrated interfaces.
The control electronics of the INV have been designed on the basis of
state-of-the-art microcontroller technology. By using parameters in
the software, the main unit characteristics are determined.

Figure 2 illustrates the principle of an INV.
In normal operation, the load is supplied "Online" by the INV. With
systems comprising several parallel INVs, the load current is divided
in accordance with the number of INVs. Depending on the system
design, a power supply using up to 8 INVs can be realised. In addition
to the parallel operation of several INVs, the reliability of supply can
be further increased by integrating a static bypass switch, SBS. In the
event of a failure of several INVs, switchover to the mains takes place
without any interruption. Apart from power cabling, a bus line is
required for control purposes between the units for systems
comprising several INVs (and SBSs). The bus line has to be
terminated at both ends with a resistor.
ATTENTION:
This INV must not be connected in parallel to the mains on the output
side!
2.4
Principle of Operation of the INV, Electrical
After connection of the DC voltage, the DC filter capacitors are
charged via the softstart device. The control unit activates a bridging
contactor as soon as the capacitor charging process is finished. The
DOU displays measured values (output voltage/output current) on the
LCD and the unit status via LEDs. The INV is switched on using the
ON/OFF switch on the DOU. When the INV has been switched on, it
can be started or stopped by connecting or disconnecting the
DC voltage supply.
The transistor INV set, pulsed with approx. 20 kHz, transforms the
direct voltage into a single-phase sinusoidal AC voltage. The voltage
is transformed electrically isolated to the required AC output voltage
using a transformer. The secondary voltage is led to the load
terminals via the AC filter, a miniature circuit-breaker, a current
transformer and the INV output contactor. The stabilised output
voltage of the INV is short-circuit-proof and can supply loads from
capacitive through ohmic to inductive, as well a non-linear loads with
a high crest factor. The INV also supplies high starting currents for
motor loads. Refer to chapter "Technical data" for the exact
specifications. The entire control and monitoring process is carried
out using a microprocessor. LEDs and relays show the unit status,
whilst output voltage and output current are displayed on an LCD.
INVs for parallel operation need a choke between the INV output and
the busbar. When several INVs are operated in parallel, or one or
more INVs are operated with an SBS, a CAN bus is required between
the units for control purposes. An additional CAN bus allows the unit
to be integrated in a power supply system and connected to a central
control and monitoring unit (PSM).
With individual units, the INV immediately starts after actuating the
ON/OFF switch. With an INV with SBS and presence of the mains,
the INV starts immediately, but the output contactor is only switched
on after synchronisation with the mains. With systems comprising
several INVs, these synchronise to the mains and then jointly switch
on the output contactor. The INV can be switched off in every
operating status without delay using the ON/OFF switch.

2.5
Description of the SBS
Its electronic high-performance components make the SBS highly
overload-resistant and thus capable of quickly eliminating load short
circuits.
The SBS can be used as the central SBS for parallel operation of up
to 8 INVs.
Another outstanding characteristic of the SBS is its communication
capability with other systems via integrated interfaces.
The control electronics of the SBS have been designed on the basis
of state-of-the-art microcontroller technology. By using parameters in
the software, the main unit characteristics are determined.

Figure 3 illustrates the principle of an SBS.
In normal operation, the SBS is not fired, the load is supplied "Online"
by the INV or INVs. If the supply of the load is no longer guaranteed
by the INVs or the load voltage has dropped below a permitted value
due to a load short circuit, the load is switched over to the mains
without interruption.
Apart from power cabling, a bus line is required for the SBS for
process control purposes between the INV/INVs and the SBS. The
bus line has to be terminated at both ends with a resistor.
Page 15 of 42
8000012364 BAL, en
"UniVert 2" inverter
2.6
Principle of Operation of the SBS, Electrical
If the SBS is supplied by connecting the mains or the load voltage,
the corresponding operating status is automatically activated after
3 to 5 seconds.
With mains operation, the DOU displays load voltage and SBS
current. With all other operating statuses, in addition to the load
voltage the corresponding status (ready, blocked, fault) is displayed.
The toggle switch on the DOU serves exclusively to acknowledge
SBS faults.
The SBS control unit continually monitors the load voltage and, in the
event of a load voltage deviation, initiates switchover of the loads
from the INV/INVs to the SBS without interruption. Then the loads are
automatically switched back to the INV/INVs. The thyristors of the
SBS only quench when the supply of the loads is guaranteed by the
activation of the output contactors of the INV/INVs.
When the SBS is fired, both antiparallel thyristors are triggered over
the whole period ensuring reliable operation of the SBS in the entire
range from inductive to capacitive load.
The entire control and monitoring process is carried out using a
microprocessor. LEDs and relays show the unit status, whilst the
output voltage and output current are displayed on an LCD. If the
SBS is operated with one or more INVs connected in parallel, a CAN
bus is required between the units for control purposes. An additional
CAN bus allows the unit to be integrated in a power supply system
and connected to a central control and monitoring unit (PSM).

Function of the Inverter
For technical data or unit settings, refer to the Technical Data Sheet
in chapter 8.
3.1
DC Input
The inverter is operated with 48 V (or 60 V) DC voltage. The input
voltage is fuse-protected outside the INV. For details, refer to the
technical data.
An integrated softstart device limits the making current of the inverter
to a value smaller than the rated input current. The input voltage is
continuously monitored. (See chapter 3.3.)
3.2
AC Output
The INV output voltage is regulated to 230 V 50 H (see chapter 3.9)
and monitored (see chapter 3.5). With an output voltage present and
the INV in operation, the green LED lights up "UO OK".
3.3
DC Input Monitoring System
If a value falls below the "DC undervoltage, switch-off" threshold, the
INV is immediately switched off. If the input voltage rises above the
acknowledgement value, the INV is switched back on. If the
monitoring system is triggered, the red "UI<" LED lights up.
It the "DC overvoltage, switch-off" threshold is exceeded, the red
"UI>" LED lights up and the INV is immediately switched off. If the
value falls below the "DC overvoltage, switch-off" acknowledgement
value, acknowledgement is made after a delay of 15 seconds.
3.4
Temperature Monitoring System
Overtemperature is signalled by the red "ϑ>" LED if the heat sink
temperature exceeds critical values. The faulty unit switches off after
40 seconds. Acknowledgement is made when it has cooled down.
Overtemperature can result from e.g. high ambient temperature,
constant overload of the INV or from fan failure.
3.5
Output Voltage Monitoring System
The INV output voltage is regulated to 230 V 50 Hz (see chapter 3.9)
and monitored. With an output voltage present and the INV in
operation, the green "UO OK" LED lights up. When the output voltage
drops below 90% of the rated value, e.g. due to overload, short circuit
or the triggering of a miniature circuit-breaker, the INV switches off
after 2.5 seconds. The unit is not automatically switched back on.
3.6
Monitoring of Functions
After connecting the input voltage, the self-test of the microcontroller
control system is carried out automatically.
Page 17 of 42
8000012364 BAL, en
"UniVert 2" inverter
3.7
ON/OFF Switch
The inverter is set ready for operation using the DOU switch on the
front panel. The monitoring functions with their respective messages
are only active when the inverter is switched on. After switch-off, all
faults are acknowledged. The settings of the DIL switches are only
accepted if the unit is switched off!
3.8
CAN Bus Interfaces X6 / X7
The unit can be controlled and monitored using the 10-pin CAN bus
connector X6 if the INV is installed in a power supply cabinet with
PSM control unit.
The CAN bus connector X7 has no significance if one inverter in
single operation operated without SBS. Both ends of the bus have to
be connected to a terminating resistor when several INVs are
operated in parallel!
For operation with SBS, only the end of the bus on the INV must have
a terminating resistor connected; a bus terminating resistor is
integrated in the SBS! (See Figure 1.)
3.9
DIL Switch
An 8-pin DIL switch is arranged below the LCD. All settings of /
changes to the DIL switch are only activated after the INV has been
switched off using the ON/OFF switch. It is counted from the left S2.1
to the right S2.8, switches that are pushed in at the bottom signify
"open"! The setting of the switches is shown on the display as a
check whenever a change is made; 0 = open; 1 = closed.
Switches S2.1, S2.2 and S2.3: Number of parallel INVs in the
system
The settings must be the same on all INVs and the SBS!

The unit is equipped with a liquid-crystal display. When the unit is
switched off, the LCD shows "OFF", when the unit is switched on it
shows the INV output voltage and output current. While the INV starts
up and output contactor K7 is still switched off, "READY" is signalled.
In the event of a fault, the 1st display row shows "FAULT" and the
2nd display row shows the type of fault.
The INV voltage and current values are displayed with three decimals
before and one decimal after the decimal point. The display accuracy
corresponds to class 1 with respect to the rated output value of the
unit.
Remote signalling is carried out by means of potential-free contacts
via a Combicon connector on the front of the unit.
Assignment of the signal terminals:
INV fault:
In the event of a signal, X10.2 – X10.3 or X3.2 – X3.3 close.
No fault: X10.2 – X10.1 or X3.2 – X3.1.
When the INV is disconnected from the power supply (no DC supply),
a fault is signalled!
The remote signals are designed for safe isolation. The minimum load
should not be below 12 V and 0.1 A.

Function of the SBS (optional)
For the technical data or unit settings, refer to the chapter “Technical
Data”.
4.1
Operating Statuses
The following operating statuses are possible:
"PowerUp":
Status after PowerUp or Reset. The control system checks the
ambient conditions.
"on":
Mains operation: The SBS supplies the load.
"ready":
In the event of load voltage deviation or INV failure / switch-off, the
SBS takes over the load without interruption, i.e. the SBS control
system switches over to the "on" operating status.
"blocked":
The SBS control unit is blocked. In the event of load voltage deviation
or INV failure / switch-off, the SBS does not take over the load, i.e.
the SBS control system remains in the "blocked" operating status.
The operating status "blocked" is activated in the event of mains
failures or phase deviations.
"Fault":
A fault has occurred in the SBS. This fault must be remedied and
acknowledged using the Reset button.
ATTENTION:
If the INV is switched off in the event of a blocked or faulty SBS, the
loads are no longer supplied with power.
4.2
Switchback Attempts
Should the load voltage deviate excessively e.g. due to overload of
the INVs or load short circuits (see chapter 4.4), the loads are
automatically switched over to the SBS without interruption. Then the
loads are also automatically switched back to the INV. It this
switchback attempt fails, the SBS continues to supply the loads. After
3 unsuccessful switchback attempts within 1 minute, the INV is
switched off and the loads remain supplied by the SBS.
Page 21 of 42
8000012364 BAL, en
"UniVert 2" inverter
4.3
AC Mains Input (X1)
The SBS is connected to a 230 V AC mains.
The input voltage is fuse protected outside the SBS. For details refer
to the technical data.
The input voltage is continuously monitored (see chapter 4.4).
When the mains voltage is present, the green "mains present" LED
lights up.
4.4
AC Busbar (X2)
The AC busbar is either supplied by the INV output voltage or the
SBS output voltage which corresponds to the SBS circuit voltage.
The INV output voltage is regulated to 230 V 50 H (see chapter 3.9)
and monitored (see chapter 3.5).
The load is only switched over to the SBS circuit if it lies within the
defined tolerances and if a load voltage deviation is detected.
4.5
AC Mains Monitoring System
When the mains voltage is no longer within the tolerance range, the
"mains present" LED goes off.
The SBS changes the operating status from "ready" to "blocked".
If the SBS is fired, the operating status does not change!
The acknowledgement is carried out automatically as soon as the
mains voltage is back within the tolerance range. The green "mains
present" LED is lit, the SBS changes from "blocked" to "ready".
4.6
AC Busbar Monitoring System
If the load voltage leaves the tolerance range, the load is switched
over to the SBS circuit without interruption. For this switchover, the
SBS must be in the "ready" operating status.
4.7
Temperature Monitoring System
Overtemperature is signalled by the red "collective fault" LED if the
heat sink temperature exceeds critical values. Acknowledgement is
made when it has cooled down.
Overtemperature can result from e.g. high ambient temperature,
constant overload of the SBS or from fan failure.
4.8
Monitoring of Functions
After connecting the input voltage, the self-test of the microcontroller
control system is carried out automatically.
4.9
Reset Button
The Reset button is used to acknowledge SBS faults. The Reset
button must also be pressed to accept the settings of the
DIL switches.
Page 22 of 42
8000012364 BAL, en
"UniVert 2" inverter
4.10
CAN Bus Interfaces (X6, X7)
The unit can be controlled and monitored via the 10-pin CAN bus
connector X6, if the SBS is installed in a power supply cabinet with
PSM control unit.
The CAN bus connector X7 is always required for communication
with the INV when operated with SBS. In this case, only the end of
the bus on the INV must have a terminating resistor connected; a bus
terminating resistor is integrated in the SBS! (See Figure 1.)
4.11
DIL Switch
An 8-pin DIL switch is located below the LCD. All settings of/ changes
to the DIL switch are only activated at mains operation, i.e. when the
operating status is "on". Also press the Reset button to take over the
settings of the DIL switches. It is counted from the left S3.1 to the
right S3.8, switches that are pushed in at the bottom signify "open"!
The setting of the switches is shown on the display as a check
whenever a change is made; 0 = open; 1 = closed.
Switches S3.1, S3.2 and S3.3: Number of parallel INVs in the
system
The settings must be the same on all INVs and the SBS!
Example: 4 INVs are in the system, at least 3 INVs should run,
i.e. 1 INV is redundant: S3.1=0; S3.2=1; S3.3=1; S3.7=0; S3.8=1

i.e. in the event of phase deviations between INV and SBS, the SBS
blocks.
If switchover with gap is selected (- S3.6 closed), the SBS does not
block in the event of a phase deviation (see chapter 4.12).

Remote signalling is carried out by means of potential-free contacts
via a Combicon connector on the front of the unit.
Assignment of the signal terminals:
SBS fault:
In the event of a signal, X4.2 – X4.3 close, no fault: X4.2 – X4.1
• When the SBS is disconnected from the power supply (no mains /
INV supply), a fault is signalled!
INV operation:
In the event of a signal, X4.4 – X4.5 close
The remote signals are designed for safe isolation. The minimum load
should not be below 12 V and 0.1 A.
4.13
Operating modes
Two operating modes can be selected using the DIL switches
(see chapter 4.11).
Switchover without gap:
The switchover from INV to SBS is always carried out without
interruption. If the INV and SBS circuit are not synchronous, the SBS
blocks. If the INV is switched off due to asynchronism or if it fails, the
load is not supplied by the SBS.
This operating mode is set ex works and is recommended.
i
NOTE:
If the mains are poor or the SBS circuit is supplied by a diesel
generator for example, the SBS can be temporarily blocked due to
frequency deviations.
Page 25 of 42
8000012364 BAL, en
"UniVert 2" inverter
Switchover with gap:
The switchover from INV to SBS is carried out without interruption if
the INV and SBS circuit are synchronous. If the INV and SBS circuit
are not synchronous, the SBS does not block in this operating mode.
If the INV is switched off due to asynchronism or if it fails, the load is
supplied by the SBS after a load voltage gap of 140 ms.
i
NOTE:
If the operating mode "Switchover with gap" is selected, the
connected loads must be able to withstand a gap of 140 ms and a
phase shift that might follow.

Start-Up
5.1
Installation
When installing the INV, the following regulations must be observed:
• The INV has been designed for use in a dry room, practically free
of dust.
• It is imperative to observe the specifications concerning ambient
temperature and site altitude (see chapter “Technical Data”).
• Severe dust accumulation or a chemically aggressive atmosphere
are not permissible; the system must be especially protected
against conductive, humid dust deposits and condensation.
• The INV functions with forced air cooling. The supply air
temperature must not exceed 45°C. The power loss of an INV is
below 340 W at rated load.
• The inverter must be installed in suitable module racks.
5.2
Connection
Before connecting the unit to the DC supply, ensure that the voltage
values given on the nameplate correspond to the supplied voltages.
The load is connected using terminals X2 (L1, N) on the front of the
unit. The DC supply is connected using terminals X1 (L-, L+). The
INV has to be earthed using a separate PE connection on the front of
the unit. The cross-section of the PE conductor must be chosen in
acc. with VDE 0100 Part 540 depending on the type of installation.
The discharge current lies below 3.5 mA. Prior to start-up, a
PE conductor connection must be established.
With earthed DC systems, only the pole of the INV DC
connection that is not earthed needs protection.
Observe correct polarity of the DC lines.
The load current must be checked before connecting the load; a
permanent overload is not permissible and has a very negative
impact on the reliability and the service life of the unit.
DIL switch (see chapter 3.9 or chapter 4.11)
CAN bus (see chapter 3.8 or chapter 4.10)
Remote signals (see chapter 3.10 or chapter 4.12)
5.3
Connecting the Loads / DC / Mains
When all lines have been connected completely, proceed as follows:
Individual INV operation:
• Switch off the INV, switch on miniature circuit-breaker F1
• Connect the DC supply (The INV has a softstart device that limits
the charging current in the input capacitors to a value below the
rated current of the unit.)
• Switch on the INV
• Connect the load
Page 27 of 42
8000012364 BAL, en
"UniVert 2" inverter
Parallel INV operation:
• Switch off the INV, switch on miniature circuit-breaker F1
• Set the DIL switches
• Insert the AC fuses
• Connect the DC supply
• Switch on all INVs one after the other
• (The output contactors K7 of the INVs start at the same time as
soon as n-R INV have been switched on)
• Connect the load
i
5.4
Individual or parallel operation with SBS
• Switch off the INVs, switch on miniature circuit-breaker F1
• Set the DIL switches (INV and SBS)
• Engage the AC fuses (INV output)
• Engage the AC mains and output fuses of the SBS
• Disconnect the manual bypass
• Connect the load
• Connect the DC supply
• Switch on all INVs one after the other
(The K7 output contactors of the INVs start at the same time as soon
as the last INV has been switched on and the INVs have
synchronised to the mains.)
NOTE:
Before switching on the INVs in parallel operation, or the SBS,
make sure the setting of the DIL switches is correct (see
chapters 3.9 and 4.11)!
INVs in parallel operation must be set to the same output voltage,
to the same number of INVs in the system and to different
addresses!
Disconnection
i
Even when switched off, the inverter can still be live due to charged
capacitors and external signals. For this reason the terminals must be
tested prior to dismantling the unit to ensure that they are
de-energised.
The capacitors can be discharged via an external resistor on
terminals X2 or X1: L+ and L-.
• Switch off the INV
• Switch off the AC fuses, if present
Switch off the DC supply
• Disable interfaces X6, X7, X3
Disconnect earthing
NOTE:
Before switching off an INV in the parallel system, check whether
the remaining INVs can take over the entire load. If necessary, the
load current must be reduced by switching off individual loads!

Maintenance
Attention! Disconnect the unit from the power supply prior to all
maintenance work. Always observe the safety instructions!
(See chapter 1.)
The INV consists of state-of-the-art components which are almost
non-wearing. We do, however, recommend regular visual and
functional tests of the unit to maintain its continuous availability and
operational reliability.
When visually inspecting the unit, check whether:
• there is any mechanical damage or foreign bodies are present,
• any conductive dirt or dust has accumulated in the unit, and
whether
• accumulation of dust affects heat supply and dissipation.
If large quantities of dust have accumulated, the unit should as a
precaution be cleaned with dry compressed air, in order to ensure
adequate heat dissipation.
The intervals at which visual checks should be performed are largely
determined by the site conditions. The unit must not be operated in
an aggressive atmosphere.

Troubleshooting
Attention! All work on the unit may be carried out by specially
trained qualified personnel only. Always observe the safety
instructions! (See chapter 1.)
7.1
No Output Voltage or Output Current Present
(with connected load)
Individual INV operation:
• DC present and correct polarity?
• Are the LCD and the fan working? (Control unit is supplied with
power)
• Is the INV switched on?
• Is the miniature circuit-breaker F1 switched on?
• Has a monitoring system responded?
(Switch the INV OFF and back ON)
With INVs in parallel operation: (additionally)
• LCD shows output voltage but no current:
AC fuse faulty? Check output voltage of the unit
INV does not synchronise and does not switch on the output
contactor
For systems with SBS: (additionally)
• LCD shows output voltage but no current:
INV does not synchronise and does not switch on the output
contactor
Is the SBS blocked?
If all aforementioned points are OK, proceed as follows:
• Disconnect the unit and disassemble it (see chapter 5.4)
• Unscrew the cover
• Observe the safety instructions!
• Check fuse F1 on printed circuit board A3.1 (softstart)
• Check fuse F100 on printed circuit board A17
(INV interface, auxiliary power supply)
• Check fuse F1 on printed circuit board A17
(INV interface, 24 V for fan, relay, INV control)
• Check plug connections for correct position
It the fault cannot be eliminated, return the unit to the works for repair
enclosing a fault description.
7.2
Output Voltage Deviation
• Did the INV cause the output voltage deviation?
• Is the unit running with current limiting due to overload?
Reduce the load!
